Abstract
The invention relates to methods and apparatus for limiting congestion in a packet-based network, particularly for controlling the transmission of voice traffic. A node in the network, such as a router, transmits at least one data stream comprising a plurality of data packets to a second node; the data streams can correspond to existing voice calls being transmitted through the network. The bandwidth utilization between the first node and second node is determined, and supervision packets are forwarded from the first node to the second node at a rate that is a function of the bandwidth utilization, the rate being inversely-proportional to the bandwidth utilization. At the second node, the congestion of the network can be determined based on the rate at which the supervision packets are received and, if the congestion exceeds a predefined threshold, the establishment of new voice calls through the second node and into the network can be limited.
Description
The invention technical field
The present invention relates generally to packet-based network, and more particularly, relate to the congested method and apparatus of restriction in packet-based network, in particular for the method and apparatus of control speech business transmission.
Background of invention
In traditional packet-oriented internet protocol (IP) network, can not guarantee end-to-end bandwidth fully.Communication end point transmits into network according to " doing one's best " principle with communication service.This means that communication end point sends to network to communication service, but when not having enough available bandwidths to transmit all communication services by the communication end point transmission, network backbone may abandon grouping.
The IP agreement such as transmission control protocol (TCP), is optimized some operation of handling transmission equipment.Such agreement can: i) increase by transmission equipment; Main frame bandwidth of sending for example; As long as between router or the bandwidth of transmission medium between network node can use (promptly not abandoning grouping); Ii) retransmit the grouping that abandons, and iii) when dividing into groups to begin to abandon, reduce the traffic carrying capacity of sending.By the reciprocation of router operation (abandoning grouping) and endpoint operation (about the response of dividing into groups and reducing the traffic carrying capacity of sending that abandons), set up a feedback mechanism through retransmitting.For fear of the vibration of this feedback mechanism, adopted a kind of Queue Management Algorithm of active, for example the early drop (RED) of earlier detection/at random at random; For example referring to Floyd, S., and Jacobson, the Random Early Detection Gateways forCongestion Avoidance of V. (be used to avoid block the gateway of earlier detection at random); IEEE/ACMTransactions on Networking (about the IEEE/ACM journal of network), Volume 1 (the 1st volume), Number in August, 4,1993,397-413 page or leaf.Before dividing into groups to be sent out, the RED algorithm monitors is used for the formation of buffering packets.Needing to adopt different priority that different grouping stream is handled is proposed by difference service (DiffServ) model.According to some differentiated service models, have three kinds of general classes of data traffic: do one's best (BE), safety is transmitted (AF) and urgent forwarding (EF).The do not divide into groups assurance that transmits of BE class of data traffic.The AF business has precedence over the BE business, and preferably is stored in for bursts of traffic and is used for delayed delivery in the formation rather than is dropped.Professional for BE and AF, need effective Queue Management Algorithm, for example RED.The EF business is superior to BE and AF is professional, and very responsive to postponing.For EF professional (for example speech business), delay must be minimized, and, if congested generation divides into groups to be dropped rather than to be postponed, because the grouping that supposition is postponed is useless to receiver.Because the EF traffic relies on short queues, traditional RED algorithm is not an appropriate method concerning the network congestion situations monitoring and reacting.
Because require the EF type communication service of low delay and low jitter phenomenon on the tranmission techniques, can not use traditional RED to detect network congestion based on formation, considered that therefore the method for replacement is controlled the professional offered load of EF.A kind of method is; The each forwarding operated all based on EF; Suppose that an end-to-end resource (being bandwidth) keeps, its expression perhaps is the professional bandwidth that keeps a quota of the EF between every pair of end points, the procotol that perhaps provides a permission between any two communication end points, dynamically to keep.Yet all there is shortcoming in these two kinds of schemes.The first, the computed volume because network is had to for the worst possible situation, fixing reservation scheme causes the poor efficiency of bandwidth and heavy excessive supply.The second, keep dynamically that protocol scheme has increased the complexity of a new volume and about the state of other disarmed state network model.
Transmit the weak version that the professional active block of EF often uses fixed reservation scheme, be similar to and be used to the professional version of traditional B E.Network is that normal load condition designs, and adds an excessive supply factor that covers improper business model.Yet if very unusual business model takes place, this scheme can cause the situation of intermediate router or link congestion.For example; Between router in same geographic area and the media gateway (MGWs); Network can have the capacity of 5000 erlang (Erlangs); Such as the east coast of the U.S. or zone, West Coast, and between the router in the router in zone, West Coast and zone, east coast, has the capacity of 1000 erlang (Erlangs).Under normal call conditions; Hope that most business rests on local zone, West Coast or zone, east coast; Wherein network capacity is 5000 erlang, and the link of the router between the thing coastal region has only 1000 erlang, and it is professional to handle worst case.Yet, under non-normal condition, (for example having thousands of sectors and move and phone local motion event), significant variation can take place in the regular traffic pattern, makes network over loading between West Coast and the east coast area router.
The IP agreement is a connectionless protocol, so whether when a new audio call is established, not knowing has sufficient network capacity between source MGWs and purpose MGWs, and therefore all callings are allowed to get into network.The consequently off-capacity of intermediate links, and router will inevitably abandon grouping randomly.The influence that all-calls is transshipped, and because the packets of voice that abandons, each user will experience bad voice quality.Under the worst situation, if the caller is hung up and retry constantly, this state may continue several hours, will cause a completely written-off speech network.RED and similar agreement use the length of formation in the router to confirm whether router is in the situation of overload.As long as being arranged, formation monitors to work fine.So it is a kind of appropriate method for BE and AF business.Weighting RED (WRED) equally works as RED, but allows different packets processing in the identical formation.Difference is accomplished according to information usually, for example DiffServ code-point or protocol fields.
Fig. 1-A and 1-B have explained the use of RED in the exemplary EF type business.According to formation fill level (shown in the trunnion axis), 0% in the formation is dropped (perhaps being labeled) to 100% grouping.In the accompanying drawings, have and be used for not two curves of business of the same race: first curve (Fig. 1-A) be used to speech business, do not divide into groups therein to be dropped (being labeled) till formation is filled and second curve (it is professional that Fig. 1-B) is used to monitoring.Shown in Fig. 1-B, even formation is only filled slightly, also there is the monitoring business of little percentage to be dropped, when queue fills, little by little the monitoring of bigger percentage divides into groups to be dropped.Yet concerning EF was professional, desirable was that hold queue length is used for minimizing the delay in the transmitted in packets to minimum.Thereby use queue length as confirming that the principle whether the EF business should be limited is not an appropriate method.
WO03/013070 discloses a kind of system of dividing into groups to flood of under the situation of grouping flood attack, preventing, wherein the assailant has used up all bandwidth of victim.Therefore, one group of transferable connection cooperation device is set up a neighborhood.Website is differentiated unwanted data and is informed that the router of transmitting said unwanted data reduces the speed that these unwanted data are forwarded.
US 2002/181401A1 discloses the business management method that utilizes allocated bandwidth in a kind of packet-based network, and it is with the basis that is calculated as to the terminal quantity relevant with the concrete business that is used for corresponding network equipment.When to being used for that the concrete professional maximum that is allowed connects or bandwidth when reading, grouping and the notice terminal of the network equipment through abandoning new calling broken off new the calling and stopped forwarding any new calling.Bandwidth is confirmed the allocated bandwidth at connection status and terminal and is retained in the current bandwidth distribution that router interface is used for the particular type communication service through calculating through inquiry periodically.If bandwidth efficient then allows other communication service.
Therefore, need a kind of improved method and apparatus to be used for limiting the congested of packet-based network technically, be particularly useful for controlling the professional transmission of EF type, for example speech business; More preferably, this improved method can easily realize in the structure of existing apparatus.

The accompanying drawing summary
In order further to improve understanding to the principle of the invention, now the following detailed description that combines accompanying drawing is made reference, wherein:
Fig. 1-A and 1-B have described the exemplary prior art that is used for the professional grouping of early drop at random (RED) of urgent forwarding (EF) type;
Fig. 2-A and 2-B according to principles illustrated of the present invention be used for the professional exemplary use of urgent forwarding (EF) type based on the RED of bandwidth; And
Fig. 3 according to principles illustrated of the present invention be used for the professional second kind of exemplary use of urgent forwarding (EF) type based on the RED of bandwidth.
Detailed Description Of The Invention
Of preamble; Utilizing queue length (actual arrays) to control as the basis whether the EF business need be limited itself is unsuitable method; Because when maybe be too late and when can have the recovery of the consume of dividing into groups, effectively packet queue shows that the EF business is higher than professional maximum a period of time of EF that scheduler program allows.Therefore, professional for EF, except that RED, need another kind of independent mechanism based on queue length.The present invention provides a kind of new mechanism to come to detect in advance the business that the abnormal traffic pattern is used for high priority delay sensitive, for example the DiffServ EF of mark IP information block.This mechanism is used in the terminal use and notices that the professional grouping of any pay(useful) load detects the EF traffic overload before abandoning, and this discarded ratio of packet of surveying professional (that is, monitoring is divided into groups) through control is realized.This mechanism can also be used for not having the call admission control that connects IP network, and does not need bandwidth to keep.Although this mechanism is similar to RED, its novelty is to divide into groups to abandon not to be independent being triggered by queue length, but is triggered by bandwidth availability ratio.
Principle of the present invention is an adjustment block transmission dispatching table so that can measure the number (perhaps by the bandwidth of transmitting the employing of dividing into groups) of grouping.Then, if dispatch list is found too much grouping (bandwidth of perhaps too much using), then abandon monitoring and divide into groups.Be dropped at first because only be classified as the grouping (being used to detect the network congestion state) of high loss priority, the present invention can be used for to the communication end point indication network congested and do not influence pay(useful) load business (it can use low loss priority to send then).Principle of the present invention is based on the novel application of the RED of bandwidth, rather than traditional RED mechanism based on formation.RED mechanism based on bandwidth is characteristic with the processes: 1) confirm the current bandwidth utilance, it can be used for each by calculating and transmit classification; And 2) according to bandwidth availability ratio, mark perhaps abandons monitoring and divides into groups; That is, monitoring divides into groups to be forwarded by the speed that is the function of bandwidth availability ratio, and wherein this speed and bandwidth availability ratio are inversely proportional to.Different abandon curve and can be used to different business types.
In an exemplary embodiment, the first step is calculated the current bandwidth utilance, and it can be performed and be used for each forwarding classification.These data typically by the most general router collect performance measurement data provide.Algorithm based on time window can be used for calculating the current bandwidth that each transmits classification; Jump window and sliding window method of measurement can be used, though the sliding window method of measurement can obtain result preferably.Length of window should be arranged to the average bandwidth utilance that allows to surpass certain intervals.
Another scheme of calculating the actual bandwidth utilance is on the basis of number of packet, it to be estimated each second.If take average packet length, count packet can be effective approximation of actual bandwidth utilance, and the classified counting of per second is than adding up to the easier computational methods of block length.
Current available traditional router support is the WRED on basis with the queue length.Some curves can be arranged to identical formation, and the curve of this coupling divides into groups to adopt classification to be selected according to each.Abandon the curve negotiating allocation list and be configured, and typically not by frequent change.Fig. 1-A and 1-B have described the exemplary static configuration of the prior art by traditional router employing.Fig. 1-A has described the curve that abandons that is used for speech business, and Fig. 1-B has described the curve that abandons that is used to monitor grouping, and wherein this abandons the function that curve is a queue length.
Basic principle of the present invention is explained in Fig. 2-A and 2-B.Fig. 2-A has described the curve that abandons that is used for speech business, and 2-B described the curve that abandons that is used to monitor grouping, and wherein this abandons the function that curve is a bandwidth availability ratio.Replace in the example like Fig. 1-A and 1-B performedly, confirm discarded ratio of packet based on queue length separately, abandon the grouping ratio and be selected as the function of bandwidth availability ratio.In exemplary embodiment, below configured threshold, do not divide into groups to be dropped, and surpass a certain bandwidth availability ratio, divide into groups to be dropped up to arriving second thresholding to increase progressively (configurable) speed.Surpass second thresholding and abandon all monitoring groupings.
Fig. 3 has described an interchangeable realization, and wherein traditional curve that abandons based on queue length is used to realize identical functions.Said embodiment can be easy on the available routers of existing employing based on the WRED of queue length and bandwidth router mechanism method of measurement, realize.Without any need for hardware change, but the software of dynamic change as the WRED of bandwidth availability ratio function must be provided.Only replace to use with discarded ratio of packet relevant with bandwidth availability ratio abandon curve (shown in Fig. 2-1 and 2-B), and use abandons curve for relevant with queue length one group with loss ratio.In the instance like Fig. 3, the curve that abandons that grouping is monitored in two different being used to is shown, and a threshold value.As shown in Figure 3, suppose bandwidth availability ratio in the scope that allows, when formation is filled, is used to monitor first of grouping and abandons curve and begin to abandon grouping.Begin to abandon monitoring grouping formation for empty even second abandons curve, and when bandwidth availability ratio surpasses threshold value, use this to abandon curve.Additional function is used for choosing two and which abandons in the curve is used to monitoring and divides into groups.As long as bandwidth availability ratio is lower than threshold value, just adopt the curve that abandons of moderate drop rate, divide into groups so only when queue fills the time, to be dropped.On threshold value, use second to abandon curve, and abandon the monitoring grouping of certain percentage, even formation is empty.In other embodiment, can adopt other curve by different threshold triggers.For example, a kind of permission abandons 50% monitoring divide into groups (even formation is for empty) when bandwidth availability ratio is higher than rank 1, and when bandwidth availability ratio is higher than higher rank 2, abandons the configuration that 100% monitoring is divided into groups.The method that the described dynamic operation of many realizations is arranged in router.In interchangeable technical scheme, there are two kinds of solutions more desirable: perhaps dynamically to reconfigure and abandon curve or reconfigure packet type as the bandwidth availability ratio function.Abandon curve for dynamically reconfiguring, the curve quantity of each formation need not change, and abandons operation but maybe dynamic changing curve change.For dynamically reconfiguring packet type, a certain abandon the grouping that curve is used to be about to be transmitted before, need earlier through a set type, the type is confirmed the curve that will on dividing into groups, use.In current available conventional router, support common basis and multi-field type.Yet possibly transmit at each increases curve quantity in the type; For example from being used for two curves that " pay(useful) load " and " monitoring " divide into groups to being used for " pay(useful) load ", three curves of " monitoring under the threshold value " and " monitoring on the threshold value ".This will allow dynamically reconfiguring based on the packet type of bandwidth availability ratio.When traffic carrying capacity was lower than threshold value, " being lower than the monitoring of threshold value " curve should be used to monitoring and divide into groups, and when business surpassed threshold value, type was used " monitoring on the threshold value " curve to be reconfigured by reconfiguring.
Other benefit of the present invention is when bandwidth availability ratio increases, and the reduction of the forwarding rate that monitoring is divided into groups is as the congested indication in the main line.The new entering network of network node of calling out of control can have a relevant threshold value of speed of dividing into groups with the reception monitoring; If speed surpasses threshold value; The new call establishment that gets into network can be limited, and helps to guarantee to keep enough bandwidth like this and is used for all existing callings and does not abandon the packets of voice relevant with these callings.
From above-mentioned, the technical staff in said field should be realized that the invention provides a kind of improved method and apparatus is used for limiting the congested of packet-based network, in particular for the transmission of control speech business.Though the present invention has carried out detailed explanation,, it may occur to persons skilled in the art that said example embodiment is carried out various changes, replacement and replacement not breaking away under the situation of the spirit and scope of the present invention of wide in range form.Said example embodiment has described principle of the present invention and this example embodiment is not completely or wants the present invention is defined as disclosed form; Its meaning is the restriction that scope of the present invention only receives listed hereinafter claim and their equivalent.
